Information

This example validates Buildings.Controls.OBC.ASHRAE.G36.Plants.Chillers.Pumps.ChilledWater.Subsequences.EnableLag_primary_dP. It validates the conditions for enabling and disabling the lag pump.

  • At 2.8 minutes, the condition for enabling the lag pump becomes satisfied and it lasts more than 10 minutes. At 12.8 minutes, the lag pump enabling output becomes true.
  • At 34 minutes, the condition for disabling the lag pump becomes satisfied and it remains true for more than 10 minutes. At 44 minutes, the lag pump disabling output becomes true.
